the Rc which removes the prostate is not bad. Dad didnt need his urethea removed but i can tell you two facts.
#1- Porstate cancer has similar tissue to the bladder and it is common for the cancer to travel there. you dont need the prostate just the nerves. if you get an experienced surgeon they are able to do so frequently. my dad eneded up having prostate cancer also so if he didnt have it out, he could have died from going undiagneosed with that.
#2-You chance of survival is much greater with your bladder removed. If you wait too long it wont be a viable option and the other options arent pretty.
